Manual winding (Cal. 2755 QP). 45 jewels. 18,000 vibrations/hour. Power reserve approximately 58 hours. Titanium case (44.5mm diameter, 13.1mm thickness). 3 ATM water resistance. Made to order.

Vacheron Constantin's "Overseas Grand Complication Open Face" combines the sporty yet elegant concept of the Overseas with the highest level of watchmaking technology, including intricate complications and high-quality finishing. It is a masterpiece truly worthy of being called a flagship model, a fusion of the Maison's worldview.
This timepiece adheres to the Overseas design code, incorporating the Maison's iconic Maltese cross, while maintaining a practical thickness of 13.1mm and incorporating ultra-complex mechanisms such as a minute repeater, tourbillon, and perpetual calendar. This is made possible by the Caliber 2755 QP movement, which is only 7.9mm thick. Located at the 9 o'clock position when viewed from the case back is a unique centrifugal adjustment system that operates silently using centrifugal force while precisely controlling the rhythm of the hammer strikes. The inertia rotor of this adjustment system is finished with perlage and engraved with the initials of Jean-Marc Vacheron, who founded the Maison in 1755, symbolizing its history and technological advancements. Furthermore, the perpetual calendar boasts high precision, requiring no adjustment until 2100, making it a masterpiece worthy of a flagship model.
The case and bracelet are made of lightweight, sporty Grade 5 titanium, finished with fine satin, matte, and high-quality polished finishes. Furthermore, this model features a sapphire crystal dial, allowing for three-dimensional viewing of the perpetual calendar, controlled by gears and levers, and the original tourbillon design shaped like the Maltese cross, from various angles.
